CAPSU LE-FILLER.

SPECIFICATION forming part of Letters Patent No. 545,365, dated August 27, 1895.

Application filed May 14, 1894. Serial No. 511,193. (No model.)

To @ZZ whom z5 may con/ocra:

Beit known that I, ALBERT M. INGALLS, of Duluth,"in the county of St. Louis and State of Minnesota, have invented a new and lm proved Capsule-Filler,of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved capsule-filler which is simple and durable in construction, very effective in operation, and arranged to permit of conveniently and rapidly filling capsules with the desired amount of medicinal and other material.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar letters ot' reference indicate corresponding parts in all the figures.

Figure l is a perspective viewot the improvement. Fig. 2 is an enlarged transverse section ot the same on the line 2 2 of Fig. l, and Figs. 3 and 4 are like views ot' the same with parts in different positions.

The improved capsule-filler is provided with a suitable stand, having a base A, a post B, and a socket C, adapted to support a removable funnel or hopper D,-into which the material is placed for filling the capsule, as hereinafter more fully described.

On the lower end of the funnel D is held a downwardly-extending iilling-tube E, made of flexible material, such as rubber, and terminating a suitable distance above the top sur- Aface of the base A. The inner diameter ofthe flexible filling-tube E is somewhat less than that of the lower end of the funnel D. The latter is held in place in the socket C by a fixed prong C and the catches F, pivoted on top of the socket near the front forked end thereof, as will be readily understood by reference to Fig. 1.

A plunger or rammer G is used in connection with the funnel D and tube E, and this plunger is double ended, and is formed at one end with the rarnming portion G and at its other end with the concavity G2 for placing the'capsule-cap Il in proper position on the body l-I after the latter is filled and packed with the substance I.

The device is used as follows: The operator first places the capsule-body H over the end G ofthe rammer or plunger G, and then passes this end ofthe plunger downward through the funnel D into the filling-tube E to expand the latter, and finally to Withdraw the plunger, so as to leave the capsule-body H in position in the expanded flexible tube E. (See Fig. 2.) The operator next introduces the desired amount of the substance to be filled into the capsule into the funnel D, so that the substance passes down into the tilling-tube'and into the capsule-body H, extending upward at its open end. The operator now uses the end G of the plunger or ramxner G to iill and pack the substance as much as possible into the capsule-body H, and then inserts the capsuie-cap H into the concave end G2, and then passes this end of the rammer downward through the hopper D into the flexible tube E to linally press the capsule-cap into position in the capsule-body l-l, as is plainly illustrated in Fig. 3. By this arrangement or process all the material or substance is firmly packed into the capsule, and by a further downward pressure of the plunger G the filled capsule is forced out of the iiexible tube E to drop out of the cavity G2 and to fall upon the base A. The operation is then repeated to till a second capsule by first introducing the capsule-body H, then iilling the same with material and ramming it, then introducing the capsule-cap H by the recessed end-G2 ot' the plunger G, as above described.

The funnel D is preferably made of hard rubber, so as to prevent adhesion of the material under treatment.

The plunger Gis formed with a central bore or aperture G to permit of readily withdrawing the plunger after the capsule-cap l-I is introduced in the iiexible tube E, as no vacuum can now fortnin the inner part of the concave end G2 on removing the latter from the capsule-cap I-l.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A capsule filler, comprising a funnel provided at its outlet end with an expansible and contractible tube to receive and hold by contraction a capsule body while being filled, and a double-ended reversible rammer provided with a, longitudinal bore serving as an air vent, substantially as described.

2. A capsule filler, comprising a stand or support, a funnel mounted movably thereon and provided at its lower outlet end with an Vexpansible tube to receive and hold by contraction a capsule body, While being filled, the bore of said tube being smaller than the eapsule to be filled and of the sanne diameter lVitnesses:
